Voltage Reference

2.048 Vshunt referencemicropowerSOT-23-3D gradeTexas Instruments

LM4040D20IDBZR is a 2.048 V D-grade micropower shunt reference for low-current reference and monitoring circuits from -40°C to 85°C.

Best for

  • Low-power 2.048 V reference rails
  • Data-acquisition reference circuits
  • Power-supply monitoring

Avoid if

  • Applications requiring tighter than D-grade initial accuracy without calibration
  • Circuits unable to guarantee the minimum cathode current

Check before use

  • Worst-case cathode current with maximum load and minimum supply
  • Reference-voltage error budget over temperature
  • Correct SOT-23 substrate pin handling
